Buckner: "Considering that the DIN only goes to 10, I'd be skeptical. That said, I've never used them."Well, I've used them extensively, and can give you a real answer. I'm not sure why you'd ever want to do a 12-foot drop onto packed powder with an AT binding (or any binding for that matter), since the purpose of alpine touring is to find untracked powder, but if you have to, these bindings would hold up the same as any other binding would at a given DIN rating. If an alpine binding set at 10 DIN will keep your skis attached while performing such "tricks," then these will too. That's what the DIN standard means. Still, Dynafit's objective is to make the lightest touring bindings in the world, and they require a certain amount of operator care and precision. If you're really interested in abusing your equipment, you're better off with an alpine binding.Buckner: Apologies that I can't provide a "real answer," but as you mentioned, DIN is a standard. Hence consistent amongst all good quality bindings. Since DIN is correlated with force, the force of a 12 foot drop could potentially kick off a binding unnecessarily that's set on 10. Ie the guy could have skied out of the landing despite a force that was strong enough to cause a binding release on a DIN of 10, whereas this release would not have occurred on a DIN of 12. Thus proper DIN needs are dependent on the forces a skier generates, thus his strength, height, weight and ability. I'm 170lbs and ski on a DIN of 12 on a salomon binding. It has always released when I needed it to, and never has released prematurely (knock on wood). If you're hitting 12 foot drops and weigh 160-170lbs or more, you're a good skier that could use a binding with a DIN of 12. Not 10. Just my $0.02. Plus, maxing out a spring likely reduces the longevity of the binding. In other words, it makes sense to ski at DIN 10 on a binding that goes to 12 versus skiing a binding set on DIN 10 that only goes to 10.For a simple answer, I have been skiing a pair for 5 years, in bounds, mostly out of bounds touring, but drops, pillows, hard skiing,the works, and they are bomber!
